This research report is a first step of a long-time effort aimed at establishing a well-coordinated set of case studies on urban development and the carbon cycle in the Americas. A two-fold purpose lies behind this endeavor. The authors intend firstly to further develop two research priorities identified by the Global Carbon Project (GCP): understanding the consequences of different pathways of urban development on the carbon cycle, and identifying points of management and intervention aimed at designing less-carbon intensive development pathways. The authors seek secondly to integrate those studies with the ones underway within other programs and institutional umbrellas.

Hazardous contaminants will be released from treatment, storage and disposal facilities (TSDF’s), industry, government facilities, households, and other everyday institutions regardless of the control measures implemented. Therefore, the fate and transport of a
contaminant is an important issue in hazardous waste management.
A key objective of the Toxic Substances Hydrology (Toxics) Program is to understand the physical, chemical, and biological processes that control contaminant transport in surface water.
A key objective of the USGS Toxic Substances Hydrology (Toxics) Program is to understand the physical, chemical, and biological processes that control contaminant transport in ground water.

This report reviews the drivers around the recent rush to biofuels and provides a snapshot of this technology and its potential. It also attempts, using a â€œsystems thinkingâ€ approach, to reframe the debate from one of technology to one focused on the services that transportation fuels provide and the factors that shape these services in the global economy. Through this lens, a range of options that are more economically, socially and environmentally attractive than biofuels come to the fore.
Biodiesel is the first and only alternative fuel to have a complete
evaluation of emission results and potential health effects
submitted to the U.S. Environmental Protection Agency (EPA)
under the Clean Air Act Section 211(b). These programs include
the most stringent emissions testing protocols ever required by
EPA for certification of fuels or fuel additives. The data gathered
complete the most thorough inventory of the environmental
and human health effects attributes that current technology will
Biodiesel is a clean burning alternative fuel, produced from
domestic, renewable resources such as plant oils, animal fats, used
cooking oil and even new sources such as algae. Biodiesel contains
no petroleum, but it can be blended at any level with petroleum
diesel to create a biodiesel blend. Biodiesel blends can be used
in most compression-ignition (diesel) engines with little or no
modifications. Biodiesel is simple to use, biodegradable, nontoxic,
and essentially free of sulfur and aromatics.
Automated People Movers 2009 is the twelfth in a series of international conferences that bring together transportation professionals to share the latest ideas, technology, planning, and projects. This yearâ€™s theme, â€œConnecting People, Connecting Places, Connecting Modes,â€ reflects the global focus on the importance of automated transit and its practical application in urban areas across the world.
